Recently, Deb got tickets for us to go to an outdoor cinema.
“It’ll be lovely”, she said, “we can have a picnic on a warm summer’s evening whilst watching a film”.
“Sounds good”, I said, trying hard to overlook the fact that, in England, a summer’s evening is as likely to be wet as it is to be warm.
Fortunately the weather held, the picnic was delicious and the company, needless to say, was divine.
As for the film…”I can’t believe that you’ve never seen Mama Mia before”, exclaimed my better half.
Some intensive negotiations followed on the subject of Brownie Points. As a result, my late Saturday evenings for the next three months will definitely include watching Match of the Day. Yes, I will get to watch A Man After Midnight. Continue reading →
Dynamic. That’s a positive word if ever there was one. Ascribing this adjective to anything would convey an image of energy and forward momentum.
On the question of Dynamic SQL, the images are rather more equivocal.
On the plus side, Native Dynamic SQL gives you the ability to :
execute DDL statements from within PL/SQL programs
code for instances where the required DML statement is not known ahead of time
On the flip side, it can also mean code that is:
difficult to read and maintain
prone to performance problems
To wander through this minefield, I have enlisted the support of a world where DRS does not stand for Dodgy Review System.
Yes, it’s the wacky and entertaining (not always intentionally so) world of Formula 1… Continue reading →
It is a strange time in the UK.
I’m not referring to England being 2-0 up after 2 tests in the Ashes (something that happens about as often as a Briton winnng the Men’s Singles at Wimbledon), nor the fact that a Briton has won the Tour de France for the second year running.
Stranger even than that is the bright yellow ball in the sky which has replaced the traditional warm rain of the British Summer.
This phenomenon has had a strange effect on the cat. Her animal instincts obviously alerted by the unfamiliar change in the climate, she currently spends almost all of her time out in the garden.
Unfortunately, she seems to have decided to treat said garden as something of a litter tray. This will necessitate something of a mine-sweeping exercise before I next mow the lawn.
It’s frustrating when you’re anxious to start something but then hit an unpleasant roadblock.
For example, you may have decided to have a play with that Oracle XE/Apex installation on your laptop that you haven’t used for a little while. However, when you come to connect, you realise that you can’t remember the password.
Health Warning – Before I go any further, I should point out that doing this is not something I’d recommend on anything other than a system that’s being used simply as a playground for you to experiment and which contains no sensitive data.
Fat, bald, likes a drink and a smoke. No, not me. That’s a description of Darren Lehman, the new coach of the Australian Cricket Team.
Sounds like a good bloke to me.
As a cricket fan, with the Ashes as the highlight of the sporting summer, I’m getting a horrible sense of deja vu.
If you read the press, Australian and English, you might be forgiven for thinking that the series is a foregone conclusion.
Yes, England should win, on paper. However, unless the groundsmen at the relevant venues have been doing something very innovative, the Tests themselves will be played on grass.
In order to take my mind off some of the more worrying parallels with this series and the one in 1989 – when Alan Border and a bunch of Aussie no-hopers demolished England 4-0 – I’ve been looking at one of those niggling little problems that I always mean to get sorted but never quite get round to.
Generally speaking, I much prefer Linux to Windows. There is however, on area where Windows has the upper hand.
When you’re working in SQL*Plus, Windows allows command line recall and editing by default. This feature is not present in Linux by default.
However, Linux, being Linux, there is a handy utility that can implement this functionality. It’s called rlwrap.
What I’m going to cover here is :
I recently spent some time working with Venkata, an Oracle programmer and keen cricket fan :
Venkata smiling the smile of a man whose team have won the cricket world cup twice more than…er…Wales.
This post is about the fun and games involved in the bulk loading of data into Oracle – especially when it includes floating point values.
In Venkata’s honour, I’m going to explore this topic through the medium of the career of Sachin Tendulkar…
At this point it’s probably worth wandering off the point to explore some of the highlights of The Little Master’s career.
India’s tour of England in 1996 has been largely forgotten. However, it proved to be a watershed in our hero’s test career.
The first test of the series at Edgebaston was not untypical of the time – Indian batsmen skittled in conditions totally alien to them. The could only muster a paltry 219 in their second innings and none of them got beyond 18…apart from Tendulkar, ninth out for 122, made with a serenity that contrasted starkly with the chaos surrounding him.
It was in the very next match, at Lords, that India granted test debuts to two batsmen who themselves would prove quite useful over the years. Surav Ganguly marked the occasion with a century. Rahul Dravid fell an agonising five runs short of doing the same.
The fourth member of India’s vaunted middle-order announced himself in the next series we look at, against Australia.
Having been soundly beaten in the first test of the series, India came back the hard way in the second test.
VVS Laxmans 281 not out, with the not inconsiderable assistance of Dravid (180) and Harbhajan (13-196) became only the third team in the history of Test Cricket to win after following on. This against arguably the best team to have ever played the game who had their record winning streak of 16 consecutive tests ended somewhat emphatically.
The 2004/05 series against Bangladesh is included because Tendulkar’s highest test score (248 not out) was made in this series.
The 2009/10 series against South Africa is indicative of the journey that India made during the course of Tendulkar’s career.
At this time they were vying with South Africa for the status of the world’s leading test nation.
Back to the techie stuff. What I’m going to cover is :
What happens when you insert a floating point value into an INTEGER column
I got a new ( and possibly new-fangled) phone recently.
Having spent a suitably geeky amount of time exploring the new features of this slab of Android lovliness I did come across something which left me quite stumped… somebody rang me up on it.
Increasingly frantic tapping of the little green phone icon failed to result in me answering the call.
It was at this point that Deb took pity and explained in that ever-so-patient way people use to the hard of thinking, that I simply needed to swipe.
Needless to say, she’s not ever mentioned the incident again and would never dream of taking any opportunity to bring it up to elicit a laugh at my expense. Ahem.
It’s unfortunate that I also got a work phone recently and spent five minutes tapping the screen before I worked out that the Blackberry I was holding was not, in fact, a touch-screen device.
As the fast-paced world of consumer electronics passes by in an ever-increasing blur, I’m comforted by the fact that I can still learn something new.
For example, I was recently faced with a situation requiring me to load data from one table into two further tables, depending on certain criteria.
With the aid of my trusty netbook ( a form-factor that is apparently as outdated as it’s owner), I shall now demonstrate the wonder of the age that is the multi-table insert statement. Continue reading →
Guilty pleasures. For some, it’s a “diet” burger with “diet” fries, washed down with a “diet” shake. Others have a penchant for Kurt Geiger shoes. “I’m Welsh and I’m worth it”, they may well say. It may even be that Def Leppard track nestled in your playlist between Coldplay and Oasis.
In programming terms, APEX seems to fall into this category for me. On the one hand, it’s a declarative development environment. This means that, unless you’re very careful, the application you write for it is not going to be too portable to other front-end technologies. But, oh, it’s so nice to be able to bang out a bit of SQL and/or PL/SQL, click my mouse in the right place, and have a nice GUI application drop onto my browser.
If you’ve decided to try the latest and greatest APEX version on your XE installation, you’ll notice that the default Database Welcome Page disappears after the upgrade.
Rather than hunting around for it, I’ve decided to knock up something a bit better…well, different.
So, if you’d like to know how to get some interesting configuration information out of the database…or just want the entertainment value of watching me blunder about in APEX then read on… Continue reading →
